Distinct Clusters of Symptoms That Can Advance to Alzheimer’s

A study has identified four distinct clusters of symptoms, including psychiatric and cardiovascular, that can progressively lead to Alzheimer’s disease — an ageing-related condition in which memory and speech steadily declines, eventually disrupting daily activities. Researchers from the University of California, Los Angeles, US, said the study offers new insights into how the disorder can develop over time rather than from isolated risk factors. Common diagnoses preceding depression can include hypertension, type 2 diabetes and intestinal disorders, the team said.
